Robust Integration of High-level Dispatchable Renewables in Power System Operation
Hongxing Ye, Jianhui Wang, Zuyi Li
The increasing penetration of Renewable Energy Sources (RES) requires more Flexibility Resources (FR), generally thermal units and storages, must be kept in the system to accommoda…
Robust Risk-Constrained Unit Commitment with Large-scale Wind Generation: An Adjustable Uncertainty Set Approach
Cheng Wang, Feng Liu, Jianhui Wang +4
This paper addresses two vital issues which are barely discussed in the literature on robust unit commitment (RUC): 1) how much the potential operational loss could be if the reali…
Dynamic State Estimation for Multi-Machine Power System by Unscented Kalman Filter with Enhanced Numerical Stability
Junjian Qi, Kai Sun, Jianhui Wang +1
In this paper, in order to enhance the numerical stability of the unscented Kalman filter (UKF) used for power system dynamic state estimation, a new UKF with guaranteed positive s…
Risk Mitigation for Dynamic State Estimation Against Cyber Attacks and Unknown Inputs
Ahmad F. Taha, Junjian Qi, Jianhui Wang +1
Phasor measurement units (PMUs) can be effectively utilized for the monitoring and control of the power grid. As the cyber-world becomes increasingly embedded into power grids, the…
Long-Term Stability Analysis of Power Systems with Wind Power Based on Stochastic Differential Equations: Model Development and Foundations
Xiaozhe Wang, Hsiao-Dong Chiang, Jianhui Wang +2
In this paper, the variable wind power is incorporated into the dynamic model for long-term stability analysis. A theory-based method is proposed for power systems with wind power…
Further Discussions on Sufficient Conditions for Exact Relaxation of Complementarity Constraints for Storage-Concerned Economic Dispatch
Zhengshuo Li, Qinglai Guo, Hongbin Sun +1
Storage-concerned economic dispatch (ED) problems with complementarity constraints are strongly non-convex and hard to solve because traditional Karush-Kuhn-Tucker (KKT) conditions…
